Detailed Description

Logs random seed used by the next RAND(), and by PASSWORD() in 4.1.0. 4.1.1 does not need it (it's repeatable again) so this event needn't be written in 4.1.1 for PASSWORD() (but the fact that it is written is just a waste, it does not cause bugs).

The state of the random number generation consists of 128 bits, which are stored internally as two 64-bit numbers.

Binary Format

The Post-Header for this event type is empty. The Body has two components:
